The effect of tide may be less than that of current...

If you sail due east, north, west and south over the ground with the
same speed over the ground and there were no current, no leeway or
other "disturbing factors", you would still not end up at your
starting point (unless....). In fact on the northern hemisphere you
would end up in a position due west of your starting point.


Well!!! Excuuuse me!

Look, I don't often get points, so I feel that I must defend them.

In most places, the effect of tide would be much greater for a 14 hour
"square" than the curvature of the Earth.
